Thanks. I appreciate the input.
I hear your point about 1 and 3 being young, although they are rather large in comparison to typical acro frags.
Checking some google images, #1 seems more A. multiacuta than A. granulosa. #3, A. loripes but it could be A. maryae. I guess I'll just have to be patient and see how they look in another 6 months or so.
Thanks again.
